I asume there is somewhere ApplicationMaster for running MapReduce Jobs, but i can't find it in documentation.

How to run MapReduce Job to specified queue (as specified user)?How to run DAG of Jobs?

If you have a 23 or 2.0 cluster all setup, yes it comes with mapreduceapplication master and you run mapreduce very similar to how you did beforeon 1.X. Have you run mapreduce before on older versions of Hadoop?

The queue can be specified the same way with"-Dmapred.job.queue.name=default".

You can run the wordcount example like - where input is file you put intoyour /user directory in hdfs and output is the output directory of thewordcount.
